The fact that there will only be two books in the series is also a new spin on the ever-popular and usual trilogy in young adult novels.

"Veronica Roth explores — with poise and poignancy — the story of a boy who forms an unlikely alliance with an enemy," the press release from HarperCollins explained. "Both desperate to escape their oppressive lives, they help each other attain what they most desire: for one, redemption, and the other, revenge."

I can't help but wonder if each book will focus on one of these two goals, perhaps narrated from each character's perspective.

It also sounds like Roth will be diversifying her writing style. Her best-selling series, Divergent, was told from the perspective of a female lead, which is also popular with the YA genre these days. Of course, publishers are always looking to diversify and doing so with an already-established author greatly increases the likelihood of success.

"I'm really enjoying working on this new series," Roth said in the statement. "I can't wait to share it with readers!"

Roth said on Twitter the new series will not be connected to the Divergent universe at all, but will be set in a completely new world.

The announcement couldn't have come at a more perfect time, since the Divergent series' second movie, Insurgent, will be released in just a few weeks on March 20.
